EDUCATIONAL APPARATUS.

SPECIFICATION forming part 'of Letters Patent No. 388,486, dated August 28, 1888.

Application filed February 23, 1886. Serial No. 192.881. (No model.)

To aZZ whom it may concern.-

Be it known that 1, Isaac FREEMAN HALL, of Leominster, county of Worcester, State of Massachusettshave invented an Improvement in Educational Apparatus,of which the following description, in connection with theaccompauying drawings, is a specification, like letters on the drawings representing like parts.

My invention relates to an apparatus for facllltating the instruction of children, being intended as a substitute for the charts or printed cards commonly used in schools.

The invention is embodied in apparatus comprising a board or frame provided with guides or holders for cards, which may have words, figures, or pictures printed upon them, and which may be supported and manipulated 1n the frame so as to form sentences or represent arithmetical or other analogous operations.

The apparatus also comprises a holder or support for the different cards to be used, so that a number may be displayed at any time and the proper ones readily selected to be used in the frame in giving the lesson.

The frame is provided with means to receive the holder when not in use, so that the two parts of the apparatus may be put together to economize space, or for convenience in handling and transportation.

Figure 1 is afront elevation of aframeforming part of an educational apparatus embodying this invention; Fig. 2, a front elevation of the holder; Fig. 3, aside elevation'of the frame having'the holder connected with it; Figs. 4 and 5, face views of the cards on a larger scale; and Fig. 6, a sectional detail on line ac m, Fig. 2, on a larger scale.

The apparatus comprises a frame, a, which may be of about the same size as the printed charts used for classes in primary schools, and may be composed of a thin board or other suitable material. The said frame a is provided with a number of parallel transverse guides, b, which are rabbeted or grooved, as best shown in Fig. 3, so as to receive the cards a, which may slide easily in the said grooves transversely to the board a, there being preferably sufficient space to permit the cards to slip over or pass by one another in the grooves.

The apparatus also comprises a displayingholder, d, Fig. 2, provided with means for supporting a number of the cards 0 until they are required for use on the frame a, thus enabling all the cards that may be required for alesson to be supported and displayed in convenient position and so that the desired one may be selectedwithoutlossof time. Ashereinshown, the holder 61 is composed of card-board and provided with a number of holding-clips, d, each composed of a piece of sheet metal provided at the lower end with a tongue, d (see Fig. 6,) which passes through a slit in the board 0?, so that the main portion of the piece of metal extends up at the front of the board d, forming a holder for the separate cards, as will be un derstood from Fig. 2.

Figs. 1 and 2 illustrate the method of using the apparatus in giving a reading lesson. A number of the cards are provided with pictures representing well-known objects, while other of the cards have the names of the objects printed or writtennpon them, and other cards have additional words, which may be used with the names of the objects to form simple sentences, and in using the apparatus the/75" instructor may take first a picture of an object and place it in the grooves ofa pair 0 the guides Z) of the board a, and then take other cards to form simple sentences, in which the name of the object occurs, as shown in the upper part of Fig. 1, after which the printed or written name of the object maybe used in connection with the picture, as shown in the second line of the board in Fig. '1, the name being slipped directly over the picture to conceal it, if desired. The various other methods of using the board for instruction in other subjects will readily suggest themselves.

The board a is also provided with. upright grooved pieces I), co-operating with the uppermost grooved guide I) to receive and hold a larger picture or card, as indicated at 0', than can be conveniently held in the lower guides b, and, if desired, cards may be used of suflicient size to engage the alternate guides b, as shown at 0 in Fig. 3; or they may be held between any two of the guides on the board, if need be.

The board a is provided on its rear side with grooved holding-pieces f, into which the holder d may be slipped when not in use, thus In testimony whereofIhave signed my name enabling the entire apparatus to be convento this specification in the presence of two subiently handled or stored. scribing witnesses.

I claim- 5 The frame a, provided on one side or face ISAAC FREEMAN HALL.

with transverse guides and on its other side with holding-piecesf, combined with the card- \Vitnesses: holder (1, adapted to be connected with the HENRY B. SMITH, frame by the said ho1ding-pieces, substantially GEORGE M. POWERS. o as described.
